Hi all,
On the wiki page appears several new addons.
* VFRFlight integration - integration with VfrFlight.org flight tracking/planning software (http://www.vfrflight.org)
* KML Exporter (Google Earth) - simple exporter to the KML format (yes, you can get it from Phi interface, nonetheless it is an example how to create protocol as an addon)
* VFR Flying Helper - little helper for VFR flying expecially with restricted screen estate. Includes modified map window (small one) and quick shortcuts to map, flight route, route manager, airports and radio dialogs
* LinuxTrack Head Tracker integration - integration with LinuxTrack head tracking software as an addon without need to customize/copy protocols into fgdata folders
* Additional Heli HUD's - additional HUD's specifically for helicopter flying
For more details see: http://wiki.flightgear.org/Addon#List_of_Addons
They should be usable in 2020.3.5 and above (and with current next git source code). Happy using !
